The apparatus includes a first and a second forming wire which cooperate together to define there- between a web-forming section having a first and a second end. A headbox is disposed adjacent to the first end of the forming section for ejecting the stock between the wires such that the web is formed from the stock during passage of the stock from the first towards the second end of the forming section. A first felt is disposed down- stream relative to the forming section with the first felt running contiguously relative to the second wire such that the second wire is disposed between the first felt and the web. A second felt is disposed downstream relative to the forming section and on the opposite side of the web relative to the first felt. An open roll is looped by the first felt and a suction roll is looped by the second felt with the suction roll cooperating with the open roll for defining therebetween a first press nip for pressing a first portion of water from the formed web. A backing roll is disposed downstream relative to the first nip and an extended nip press shoe cooperates with the backing roll for defining therebetween an extended nip such that the second felt and the web extend through the extended nip for removing a second portion of water from the web.
